# Observations

Observations can be used by surveyors as a tool to direct attention towards a specific point or area within the dataset. You can either manually add observations or import them from a CSV file. The added observations are automatically gathered into the report. You can select the type and severity of the observation. The observations placed before a chainage is made will automatically be added to the respected chainage upon creation.

# Add observation

You can add Point or Line observations. Observation allows the user to examine and draw attention to a specific point or line in the dataset.

In the 3D view, open **Observations** from the righ-side menu and select **Point** or **Line observation** icon from the actions. Pick points for the observations by clicking on the dataset.

| You may also place an observation by right-clicking directly on the dataset

# Import observations

You can import point observations from a CSV file by opening the ** Observations** tab and selecting **Import** from the menu actions. Select the wanted CSV file from your file browser and the observations will get added using the information included in the CSV. In order for the import to work the file needs to include four columns in the following order: X, Y, Z, Name.

# Enter observation info

Enter details regarding the observation:

* Give a name for the observation
* Choose the Severity of the observation from the classifications (Info, Slight, Significant, Severe)
* Add a description of the observation
* Add images or other attachments

|| The location of the observation will be filled by default if you have a chainage

### Add screenshots and images

* Click the **camera icon** to add a screenshot from the current view to observation or click the **attachment icon** to add an image from your files. You can also just paste an image copied on your clipboard to the open field!
* Add a name when attaching the image or screenshot

|| Change the order of images by clicking and dragging the image up or down.

# Edit observation

Click the **Observations** icon from the right-side menu to see all observations added to the dataset. Click on the observation you want to edit and modify info and add images or delete the observation. Change the order of observations by clicking and dragging the observation up or down.

# Add chainage

Adding chainage allows observations to be linked to a certain location in a dataset. If you add a chainage after you have added observations, the observations will be automatically linked to the added chainage.

Add chainage (in meters) to your survey area using this feature in the 3D view:

* Open the Chainage tab from dataset info panel
* Activate the chainage tool by clicking the **+**button
* Select points in the dataset according to the desired chainage
* Hold **Shift** to end line

|| To make exact vertical or horizontal perpendicular chainage, hold the **Ctrl** key as you click, hold the **Shift** key to end the chainage.

Fill in the details:

* Label: Identification for the chainage. Can only contain lower/uppercase letters (A-Z)
* Label distance: Distance between two labels
* Start distance: Starting number of the chainage
* Height offset: Distance above the selected points in the dataset

To edit or delete a chainage, click on the edit icon. You can change everything except for the label distance.

| If you don’t see the added chainage in dataset, please check if **Chainages** are set to be visible via layers.
